Evaluation of Radiographers Experience and Knowledge Related to Estimation, Radiation Dose Comparation, and CT Parameters in Kota Medan, Indonesia

Abstract

Introduction: In patient examination, the role of a radiographer is very important especially in applying
appropriate techniques and procedures to minimize exposure received by patients as needed or optimization.
Given this, radiographer knowledge of CT parameters is very important, especially the impact on radiation
and the quality of the image produced. Perception of the risk and estimation of CT radiation doses also need
to be radiographer’s knowledge because in the service, radiographers are the most frequently interacted with
patients.
Purpose: To assess the opinion, experience and knowledge of radiographers regarding radiation risk and CT
parameters in Kota Medan , Indonesia.
Materials and Methods: a survey study was conducted on 33 radiographers from three hospitals in
Kota Medan using a 60-question questionnaire consisting of three parts: characteristics, experience, and
knowledge. Data were analyzed using Excell and SPSS version 25.
Results: the calculation of 48 knowledge problem questions answered, the total value of each respondent is
then calculated. Average knowledge value of respondents 56.3% (poor category) with correct value range
14 - 32 with an average value of 26.1 + 4.2. None of the respondents answered all the questions correctly
Conclusion: the score of the radiographer’s knowledge of estimation, dose comparison and CT parameters
is still low. Review of knowledge, training or further courses related to CT optimization techniques need to
be attempted again in the hospital for radiographers.
